Find LCM of 641,315,987,626,235 with Prime Factorization
| 3 | 641, 315, 987, 626, 235 |
| 5 | 641, 105, 329, 626, 235 |
| 7 | 641, 21, 329, 626, 47 |
| 47 | 641, 3, 47, 626, 47 |
| 641, 3, 1, 626, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 47 x 641 x 3 x 1 x 626 x 1 = 5940743130
Therefore, the lowest common multiple of 641,315,987,626,235 is 5940743130.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
641 x 315 x 987 x 626 x 235 = 29317567346550
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
641 : 1, 641
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
987 : 1, 3, 7, 21, 47, 141, 329, 987
626 : 1, 2, 313, 626
235 : 1, 5, 47, 235
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,315,987,626,235, is 1.
Now, the common factors can be found like this.
641:641
315:3x 3x 5x 7
987:3x 7x 47
626:2x 313
235:5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 47 = 4935
Therefore, the value for common factors is 4935.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 29317567346550/(1x4935)
LCM = 29317567346550/4935
LCM = 5940743130
Thus, we can understand that the LCM of 641,315,987,626,235 is 5940743130.
